Globally, 80.3% of school-aged children do not engage in the recommended 60 minutes of daily moderate-to-vigorous physical activity (MVPA; Hallal et al., 2012). Motor skill competence is fundamental to a child’s physical activity and cognitive development (Stodden et al., 2008), and thus may explain the lack of MVPA engagement among children. PURPOSE: This study aimed to examine the effects of a fundamental motor skills (FMS) intervention program on physical and cognitive health outcomes among elementary children. METHODS: Participants were 31 K-2 students (19 girls, 12 boys; Mage = 6.65) from three public elementary schools in the southwestern U.S. They were randomly assigned to either the intervention (1 school, n = 20) or the control group (2 schools, n = 11). During two separate 8-week periods in 2017 and 2018, children in the intervention group (13 girls, 7 boys) joined the FMS intervention for three times per week (60 minutes each time), while children in the control group (6 girls, 5 boys) followed a traditional afterschool program (e.g., free play). Children’s pre- and post-intervention data were collected using the Test of Gross Motor Development - 2nd edition (TGMD-2; Ulrich et al., 2000), accelerometers (Actical), and a cognitive function questionnaire (PedsQLTM; Varni et al., 2011). To examine the intervention effect, a 2 × 2 repeated measures MANOVA was used, with group as the between-subjects variable and time as the within-subjects variable. RESULTS: The MANOVA showed significant differences between the intervention and the control group over time, F(4,26) = 16.83, p < .001, partial η2 = .72. Follow-up univariate tests for the group × time effect indicated significant differences (p < .05) in locomotor skills (intervention: MT1 = 25.4 vs. MT2 = 37.98, d =8.31; control: MT1 = 29.73 vs. MT2 = 30.32, d = 0.25), object-control skills (intervention: MT1 = 24.68 vs. MT2 = 39.78, d = 7.07; control: MT1 = 27.05 vs. MT2 = 27.59, d =0.19), and MVPA (intervention: MT1 = 143.62 vs. MT2 = 170.06, d = 2.54; control: MT1 = 166.24 vs. MT2 = 155.17, d = 0.79), but not in cognitive function (p > .05). CONCLUSION: The FMS intervention showed significant improvements in FMS and MVPA, compared to a traditional afterschool program. Findings highlight the importance of FMS for motor skill competence and MVPA promotion among school-aged children.
